When the ball will hit the ground, the height will be zero. So we need to replace

with 0 in our equation, and solve for

:


To solve this equation we are going to use the quadratic formula:

.
From our height equation, we can infer that

,

, and

. So lets replace those values in our quadratic formula to find



or


or

Since time cannot be negative,

is the solution of our equation.
We can conclude that the ball will hit the ground after
2.71 seconds.
Step-by-step explanation:

we know that
To find the company with the greatest total employee compensation package, adds each company's gross pay, paid insurance, and paid time off, then subtract the job expenses on the sum
So
Find the total employee compensation package for each company
Step 
Find the total employee compensation package for company A


Step 
Find the total employee compensation package for company B


Step 
Find the total employee compensation package for company C


Step 
Find the total employee compensation package for company D


therefore
the answer is
the company with the greatest total employee compensation package is the company C
If you would like to divide 2 by 1 6/7, you can do this using the following steps:
1 6/7 = 13/7
2 / 1 6/7 = 2 / 13/7 = 2/1 / 13/7 = 2/1 * 7/13 = 14/13 = 1 1/13
The correct result would be 1 1/13.
